These peculiar varieties are born from heavy die polishing, which was intended to remove clash marks. No FG Kennedy half dollars are popular with series specialists and have been for years. Among these varieties are the No FG Kennedy half dollars, which lack the “FG” initials of the coin’s reverse designer Frank Gasparro.
Kennedy half dollars are among the most popular United States coins, offering a wide variety of common dates, conditional rarities, and notable varieties.
